Is iFile compatible with iOS 12.1????

I have spent all night trying to install iFile on my iPhone 7 Plus so that I can stop the music sound reduction when I get alerts. When I tried to sideload on Cydia Impactor, I got an error message “Failed to find matching arch for 32-bit Mach-O input file...” etc., which I believe means that iFile is a 32-bit and my iOS is 64-bit. Right?

At any rate, after several hours I’ve concluded that there is no iFile version compatible with iOS 12.1 despite many website lies to the contrary. Am I right?
